PIVOT-LIGHT.

Be it known that we, [WILLIAM F. GREEN and Crmnnns W. .LINEKER, citizens otthe United States, residing at Modesto, county of Stanislaus, and Oakland, county of Alameda, State of California, respectively, have invented certain new and useful Improve- ..ments in Pivot-Lights, of which the follow-.

ing-isaspecification.

This invention relates to automobile lamps 5 a311d has special reference to apparatusconnectlng the lamps with the steering mecha- .nisin' so that the lamps may be turned to throw the light in conformity with the curves followed by the machine in changing its course this. invention for turning the lamps. Fig.

Theinvention has for its object to provide an improved apparatus of this kind by means of which both lamps'may be simultaneously turned as the front axle is turned by the steering mechanism, and also so that one of the lamps may be turned independently of the other and moved so as to throw the light in any. desired direction.

Referring to the accompanying draw ings':-Figure 1 is aplan view of a portion of a device for turning thelamps. 2 is andetail viewin elevation of a device shown in Fig. 1 ,with the casing removed and the upper portion of the device in elevated po- -Q-Sli2l01l. Fig. 3 is an enlarged detail view in vertical section of the device shown in Fig.

2 with the same closed. .Fig. dis a plan view of a portion of an automobile with the mechanismconstructed in accordance with 5 is a side view of the front end of an auto- -1i1obile showing the apparatus for turning clined'portion 2 which fits upon the top of a spring 3, of an automobile 4: and is detachably secured thereto; in any suitable manner. The casting 1 has projecting from its top and formed integral therewith a cylindrical casing 5 having a flange 6 at its bottom.

'Seated on the flange 6 is a cylindrical member7, secured rotatably upon'thecasing 5.

Patented time 27, 1911.

The member 7 is formed with V-shaped recesses 9 opposite each other in which are seated V-shaped projections 10 of a second cylindrical member 11, and vertically slidable on the casing 5 and surrounding the members 7 and 11 is a thin cylindrical shell or casing 12 which is fastened to the lower member 7 by means of a set screw 13 and has its upper end projecting into a cylindrical slot 14 in the upper member 11. The lower member 7 of one of the lamp supports is-p-rovided with two arms 14 and 15 projecting at a rightangle to each other and the other member 11 is formed with an arm 16 projecting in alinement with the arm let and ata right angle to the arm 15. 7

Within the casing 5 is mounted a vertical bolt 17 having a flange 18 at its lower end. .Mounted above said flange 18 on the bolt 17 is a circular steel washer 1'9 and between the washer l9 and the flange 18 are located balls 20 forming ball bearings. The upper end of the casing 5 is closed by the disk 21' upper end of the member 11. Mounted. on

the upper end of the bolt 17 and clamped against the top of the member 11 by means of a nut 24: is the pivotal portion 25 of the bracket arms 26 in which is mounted the lamp 27. Mounted on the bolt 17 within the casing 5 is a coil'spring 28 which is placed therein under considerable pressure, and has one end fastened. to the steel washer 19. It willbe seen that by means of this construction that as the arm 16 of the member ll-is pulled to cause the member 11 to rotate and by reason of the. tapering projection 10 seated in the taperihg recess 9 will be raised by the tapering projection 10 on the incline of the opposite tapering recess 9. In this movement the friction is relieved by the ball bearings hereinbefore described in the casing 5 and in the upper end of the member 11. This rotary movement of the-member 11 causes the'1amp'27 to be turned at an angle, and the coil spring 28 having been put under increased'tension by said movement when" the pull on-the arm 15 is released reacts to automatically move the member 11 back to its normal position and thereby bring the lamp 27 to normal position as shown in Fig. 4. The arm 15 projecting from the member 7 extends rearwardly from the lamp and the end of the arm 15 is pivotally connected at one end to a rod 29 the other end of which is pivotally connected to an arm 30 which extends rearward from a rotary member mounted on a support 32 secured to the spring 3 the rotary member 30 carrying the arms 31 of the lamp 32.

The lamps are turned in unison by means of a rod 32 pivoted at one end to the end of the arm 14 and connected'to an arm 33 of the regular steering gear. The rod 32 is made in two sect-ions which are held together by a sleeve 34. One 'portion'of the rod 32 is permanently fixed to the endof the sleeve 34 and the other portion of the rod projects into the sleeve 34 and is fastened by means of the set screw 35. The sleeve 34 is of such a length that during the day the set screw can be removed leaving the movable part of the rod free to work back and forth by the action of the steering gear without movingthe lamp.

Pivoted to the arm 16 and projecting from the rotary member 7 is a rod 36 which extends through a sleeved bracket 37 on the frame of the machine, and is formed in two parts connected by the sleeve 38, one of the parts of said rod terminating in the handle 39 located near the steering mechanism. The sleeve 38 which is shown in detail in Figs. 6 and 7 consists of a hollow cylindrical shell containing two longitudinal grooves 40 and a transverse circular groove .41. The movable portion '36 of the rod.

36 has its end projecting into the cylindrical shell forming the sleeve 38 and is provided with pins 42 which slide in the grooves 40. The otherportion 36 of the rod 36. is fastened in an suitable manner tothe end of the sleeve 3 When it is desired to couple the twoportions of the rod 36, the movable portionf36 is pushed into the sleeve until the pins 42 arrive at the.

circumferential groove 41 when the rod is given a turn and the pins 40 are brought into engagement with the groove 41 and thereby fasten the movable portion of the rod in the sleeve 38. e

It will be seen that by means of the construction hereinbefore set forth that the lamps are mounted on two rotary pedestals and are connected so as to rotate in unison and turn the lamps in the same direct-ion. Thisis accomplished by means ofthe rod 32 connected with the steering-mechanism.

projecting from the upper part of the ped-- estal only operates the lamp- 27, since it causes only the upper member 11 of the pedestal to rise and turn.

Having described the invention, we claim 1. In an automobile or similar vehicle, a pair of lamps, rotary pedestals on which said lamps are mounted, each of said pedestals having an arm, a connecting rod pivotally connected to the arms of said pedestals, a second arm on one of said pedestals having a rod connecting said arm with the steering-mechanism of the automobile and formed in sections one slidable from the other, one of said pedestals being formed with two rotary members and one of the lamps being mounted on one of said rotary members, an arm projecting from said rotary "member, and a rod pivotally connected to said arm and extending to a point adjacent to the steering wheel of the automobile.

2. In an automobile or similar vehicle, two rotary pedestals at the front of the machine, each having rearwardly extending arms, a rod pivotally connected at its ends to said arms, one of said pedestals being formed withtwo rotaryv members, one of which is adapted to'ride over and be lifted up by the other as it is rotated, one of said lamps being mounted on saidvertically movable member of said pedestal, a rod connecting the lower member of saidpedestal with the steering gear of the machine and formed in two parts. detachably connected together, and a rod connected with the upper movable member of the pedestal and extending to a point adjacent to the steering wheel.
